SEL-651R
Advanced Recloser Control
The SEL-651R Advanced Recloser Control offers exceptional protection and communications capabilities for Automatic Network Reconfiguration, three-phase and single-phase tripping, and other distribution automation needs. These capabilities help you maintain reliable service to as many customers as possible in the event of a fault.
Quickly commission the SEL-651R by applying just the settings you need using SEL QuickSet Design Templates. Easy-to-use Design Templates create a simplified settings interface and can be customized for your needs. Store design templates on the recloser control for quick access when making settings changes.

Applications
Speed Up Distribution Protection—Combine the SEL-FT50 and SEL-FR12 Fault Transmitter and Receiver System with the SEL-651R for more intelligent protection. The SEL-FT50 Fault Transmitters, located on branches, laterals, and the main line, will wirelessly communicate the fault location to the SEL-651R in 6 ms. This allows both fast tripping for main-line faults as well as fuse-saving and fuse-blowing schemes on the same feeder.
Customer Outage Minimization—Reduce system and customer impacts with single-phase tripping and reclosing. Improve reliability by maintaining service to customers who are not on the faulted phase of the feeder. Supported operating modes include: three-phase trip/reclose, three-phase lockout; single-phase trip/reclose, three-phase lockout; single-phase trip/reclose, single-phase lockout; and single-phase trip/reclose, single-phase lockout with three-phase lockout if more than one phase is involved.
Distributed Generation Protection—Protect both the utility and the independent power producer with one low-cost device. Apply directional protection and simultaneously use different protection settings for faults in either direction. Protect the system from voltage angle differences by enabling synchronism check before closing.
Load Shedding—Use underfrequency and undervoltage elements to implement basic load-shedding schemes. For more advanced load-shedding schemes, take advantage of the rate-of-change-of-frequency (ROCOF) elements to shed load for increasing or decreasing frequency.
Communications-Assisted Protection Schemes—Integrate the SEL-651R into either Ethernet- or serial-based communications networks with standard DNP3 and Modbus protocols or optional IEC 61850. Use communications for local and remote engineering access, supervisory control and data acquisition (SCADA), real-time protection and control, loop restoration, islanding detection, blocking, and fast bus tripping schemes.
Inrush Detection—Detect transformer energization or motor startup, and block tripping for inrush conditions with a second-harmonic blocking element. Implement the harmonic detection element to block selected tripping elements until the inrush subsides.
High-Impedance Fault Detection—Detect downed conductors and high-impedance faults with the optional Arc Sense technology. Learn more about this exciting technology.
Overview
Control Cable Interface
Select control interfaces for reclosers from ABB, Eaton (Cooper), G&W, Hawker-Siddeley, Siemens, and Tavrida. See the Recloser Compatibility table to learn more about the supported recloser models.
Enclosure
Select the painted stainless steel versions of our enclosures for superior corrosion resistance, especially in areas prone to salt or other corrosive chemicals.
LEA Voltage Inputs
Reduce costs and save space with LEA voltage inputs. Use LEA inputs for three or all six voltage input channels. Many popular reclosers have the sensors built right into the recloser bushings (eliminating the need to hang and wire potential transformers to measure the line voltages) and are supported by the SEL-651R.
High-Impedance Fault Detection
Detect more high-impedance faults than with traditional protection by using Arc Sense technology.
Additional Inputs and Outputs
Add seven inputs and eight outputs. Options include: seven 12 V inputs with five Form A outputs and two Form C outputs, or two 125 V inputs and five 12 V inputs with five Form A outputs and two Form C outputs.
Ethernet
Choose from single-fiber or dual-redundant fiber Ethernet port upgrade options.
IEC 61850
Easily integrate the SEL-651R into your IEC 61850 communications systems.
Power Supply
Select from 230 Vac, 125 Vdc, or 48 Vdc alternatives to the standard 120 Vac power supply.
Battery
Upgrade to the 40 Ah extended capacity battery to increase your operation time after a loss of ac power.
Configurable Labels
Customize your control pushbutton and target LEDs to match your application and workflow with the user-configurable label insert kit.
Tricolor LEDs
Program the pushbutton and target LEDs to display as red, amber, or green to meet your application needs and preferences.
